VlVlACHI'NE FOR CUTTING TAPERED CORKS.v

SPECIFICATION forming part of Letters Patent No. 242,304, dated May 31,1881.

Application filed March 12, 1881.

To all whom it may concern:

Be it known that I, GEORGE WASHINGTON GREENE, of Pittsburg, in thecounty of Allegheny and State of Pennsylvania, have invented anew anduseful Improvement in Machines for Outtin g Tapered Gorks and Bungs, ofwhich the following is a specification.

Figure l is a sectional side elevation of my improvement. Fig. 2 is aperspective view ot' the mandrel, cutter-holder, and sliding` collar.

Fig. 3 is a front elevation of the same, and showing the device forapplying a power-feed. Fig. 11 is a front view of the same, and showinga hand-feed. Fig. 5 is a perspective view of a saw-edged cutter. Fig.Gis a perspective view ot' a knife-edged cutter. Fig. 7 represents amodification of the cutter-mandrel.

Similar letters of reference indicate corresponding parts.

The object of this invention is to facilitate the cutting of taperedcorks and bun gs.

A represents the table that supports the machine, and to which isattached a frame, pedestal, or bracket, B.

In bearings C, attached to the frame B, revolves a shaft, D, to which isattached a pulley, E, to receive the driving-belt. One or both ends ofthe shaft D project and have screw-threads cut upon them to fit intoscrewholes in the base ofthe mandrel F. The mandrel F is tapered, and toit is secured, by screws G or other suitable means, the cutter-holder H,which is made in one, two, or more parts, accordin g as one, two, ormore cutters are to be used. The inner surface ot` the cutter-holder His so formed as to tit upon the tapered mandrel F, and its outer surfaceis cylindrical. The adjacent edges of the parts of the cutterholder Harerabbeted, forming T-grooves I to receive the cutters J, the blades ofwhich are made with serrated edges, as shown in Fig. 5, or with smoothedges, as shown in Fig. 6, accordin g as the character of the materialto be operated upon may require. The Shanks or bodies of the cutters Jare formed to tit into the T-grooves I, and upon the outer sides of thesaid shanks are formed arms K, which project beyond the outer surface ofthe cutterholder H to enter a ring-groove, L, in the inner surface ofthe collar M, so that the cutters J can be moved out and in by slidingthe said (No model.)

collar M forward and back upon the said cutter-holder H.

Upon the opposite sides of the collar M are formed gudgeons N, toreceive the yoke O, to which the power is applied to slide the cutters Jforward and back. When the collar M is to be moved forward and back bypower, the yoke O is made in the forni of a half-ring with bearings inits ends to receive the gudgeons N, and with a right-angled arm, P, uponits middle part. Upon the end of the arm l? is formed a screw-thread tofit into the screw-thread in one end of the long nut Q. The nut Q, has aright serewthread in one end and a left screwthread in the other end,and into the screwthread iu its other end fits a screw-thread formedupon the end ofa bar, R, which slides in bearings S attached to Jtheframe B. When two mandrels, F, and their attachments are connected withthe shaft D, the oppositeends of the sliding bar R are connected withthe yokes 0 of the two collars M, so that the cutters J of the onemandrel F will be pushed forward as the cutters J of the other mandrel Fare drawn back. When two mandrels are used they may be so made that themachine will cut corks or bungs of the same size or of different sizes,as may be desired. With this construction, by turning the right-and-leftnuts Q, the cutters J may be projected to a greater orless distance asthe desired length of the corks or bun gs may require.

To the center ofthe sliding bar R is pivoted the upper end of the leverT, which is pivoted to a suitable support, U, attached to the table A.The lower end of the lever T is designed to be inserted in a cam-groovein a cylinder placed beneath the table A, and revolved by a belt fromthe driving-power, so that the knives can be projected and retractedautomatically.

The cam-grooved cylinder is not shown in the drawings, as there isnothing new in its construction.

The yoke 0 may be made in the form of a ring, as shown in Fig. 4, andwhen the cutters are to be fed forward and back by hand the said yokehas stems V XV formed upon it at right angles with and equally distantfrom the bearings for the gudgeons N.

In the stem V is formed a bearing parallel IOO with the bearings for thegudgeons N to rcceive a pivoting-screw, X, which is screwed into the topot' a pedestal, post, or other support, Y. In the stem YV is secured alever or handle, Z, by means of which the operator moves the knives Jforward and back.

In a pedestal, a, placed in front of the mandrel F, is formed anopeningin which is placed a block, b, of hard woodfor the cork, wood, orother material to rest against while being operated upon by the cuttersJ, so that the edges of the said cutters will not be dulled. The block bis secured in place detachably by a setscrew, c, passing in through thetop of the pedestal af, and resting against or entering the said blockb.

To the block b or to the pedestal a is pivoted a roller, d, for thematerial to rest upon while being cut, so that it can be readilyadjusted. The mandrel I" can be arranged with its smaller end forward,as shown in Fig. l, so as to cut the larger ends of the corlrs or bun gsrst; or the said mandrel can be arranged with its larger end forward, asshown in Fig. 7, so as to cut the smaller ends ot' the corls or bungsrst.

Having thus fully described my invention, claim as new and desire tosecure by Letters Patentl. In a machine for cutting tapered corks andbungs, the combination, with the shaft D, of the tapered mandrel F, thecylindrical cutter-holder H, made to fit the mandrel F, and havingT-grooves I, the cutters J, having outwardly-projecting arms K, thesliding collar M, having interior groove L and gudgeons N, and the yokeQ,for moving the cutters forward and back, substantially as herein shownand described.

2. In a machine for cutting tapered corks and bungs, the combination,with the yoke O, hung from the sliding collar M, that moves the cuttersJ, ot' the screw-arm I), the right-andleft nut Q, the sliding bar R, andthe pivoted lever T, substantially as herein shown and described,whercby the critters can be fed forward and back by vibrating the saidlever, as set forth.
